Fluorescence microscopy confirms the DNA-mediated binding and release of small-molecule cargo anchored onto microstructured DNA-A surfaces. Schematic overview and fluorescence microscopic images of microstructured surfaces (A) after incubation with C-DNA labeled with small-molecule Cy3 fluorophore, (B) after toehold-mediated strand displacement with release R-DNA, and (C) after rehybridization of fluorescent labeled C-DNA. The line profiles of fluorescent microscopic images along the white lines of the microscopic images are shown to the right. Image size: 96 μm × 96 μm.
